Kernrechtsfrage
Whether the appeal had to be entered upon after the advance costs were not paid within the extended time limit.
Extrahierter Entscheid
The appeal was not entered upon because the advance costs were not paid even during the grace period.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the requested advance costs within the set additional deadline leads to non-entry in simplified proceedings under Art. 108(1)(a) BGG.
